GRAIL with its dual Custodial and Self-Custody models, offers a secure, efficient, and highly flexible framework for centralized entities to provide on-chain gold ownership. By defining a Distribution Partner’s kind at setup, the system adapts to support either partner-managed user assets (Custodial) or user-managed assets in their own Web3 wallets (Self-Custody).
Key features like central PDAs for KYC and partner operations, compressed user accounts for data management, and a robust authority structure are tailored to each model. This strikes an optimal balance between decentralized security, user empowerment, and centralized operational efficiency.
The open-source nature and clear pathways for future expansions like multi-asset support and DeFi integrations make it a versatile, partner-friendly, and user-centric solution for the modern financial landscape.
